CPU Module

The CPU module, displayed in Figure 11, is at the top of the chassis. This is the only slot it will work in. If it is not at the top of the chassis, the DES-5024 will not work. See Table 2: Power LED, for an explanation of the Power LED. See Table 3: CPU Module LED for an explanation of the LEDs on the CPU module.

The meaning of the Power LED is displayed in Table 2: Power LED. The meaning of the

remaining LEDs is displayed in Table 3: CPU Module LED.

Power

The power LED lights when the DES-5024 is powered on. The purpose is to confirm that the DES-5024 is getting adequate power.

Status

The Status LED indicates the status of a firmware download. The LED will increment from left to right while firmware is being downloaded. It will be dark during normal operation.

Diagnostic

The Diagnostic LED is used to diagnose any problem on the DES-5024. If any part of the DES-5024 fails the POST or if a problem occurs the Diagnostic LED displays a code indicating the problem. See Chapter 6 for the meaning of the LED code and a recommended action.

Utilization

The Utilization LED indicates the utilization of the DES-5024’s CPU. It increments from left to right. The higher the number the greater the utilization.
